We can conclude that the value of angle y is 70° and x is 35°.
What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.So, a measure of 'x':
We can see that ∠BAC = ∠DAE (Inversely opposite angles)
∠BAC = ∠DAE = 40°We can observe that △DAE is an isosceles triangle with ∠2x and ∠y being equal.Let 2x be y for instance:
y + y + 40 = 1802y = 180 - 402y = 140y = 140/2y = 70°Now, we know that y = 70 and similarly 2x = 70.
Now, solve for 'x' as follows:
2x = 70x = 70/2x = 35°Therefore, we can conclude that the value of angle y is 70° and x is 35°.

the graphs are attached herewith , where the label of the graph are :
along X-axis: 1 square division = 10 units
along y-axis: 1 square division: 10 units
The problem we dealing with is related to manipulating graphs.For the question 7 to 10, the commonly given function is f(x)= √x, if the g(x) is nothing but the f(x-c) or f(x+c), so for the g(X) to be f(x-c), then a graph of that particular function turns to stretch downward whereas, for the f(x+c), it stretches upward.
So, for 7 g(x)=√x- 4 where -4 is c so the g(x) = f(x-c) so the point for the graphs will stretch downward compare to the pint of the functions f(x)= √x.
8. g(x)=√x +3
here g(x)= f(x+3), so the pints stretched upward
9. g(x)=√x + 6 − 4=√x + 2
here additional number for the points ar 2, as it positive one, so the point of the function g(x), stretches upward
10. g(x)=√x - 7+3=√x -4
here the c is -4, so the point of the g(x), stretches downward.
Same for the questions 11 to 14, the common function is f(x) = 1/x ,for which which g(x) = f(x-c) or f(x+c), for positive c , the graph stretches upward otherwise it moves downward
11. g(x) = 1/x +4
here the c is positive, the graph stretches upward for the g(x)
12. g(x) = 1/x - 6
here the c is negative, the graph stretches downward for the g(x)
13. g(x) = 1/x-6 + 8= 1/x+2
here the c is positive, the graph stretches upward for the g(x)
14. g(x) = 1/x+7 -4= 1/x+3

What is coordinate geometry?
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that M is the midpoint of CF for the points c(4,10) and f(10,10). To calculate the segment MF first let us calculate the midpoint M.
M = [ ( x₁ + x₂ ) / 2, ( y₁ + y₂ ) / 2 ]
M = [( 4 + 10 ) /2 , ( 10+10 ) / 2]
M = ( 7, 10)
The length of the segment MF will be:-
D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]
D = √ [ ( 10-10 )² + ( 10 - 4 )² ]
D = √36
D = 6

In angle L M N the measure of angle L is equal to the measure of angle M. The measure of angle N is twice the measure of angle M. Find the measure of each angle in angle L M N
Answers
The measure of ∠M and ∠L is 45 degrees. then the measure of ∠N is 90 degrees.
How does an angle form?An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints. The point of their joint is called vertex of that angle. Those two line segments forming it are called arms of that angle. The angle is the degree of rotation that it will take for the moving side to go from initial side to the position it is currently on.
Given that the angle L M N the measure of angle L is equal to the measure of angle M.
∠L = ∠M
Also, the measure of angle N is twice the measure of angle M.
∠N = 2∠M
The measure of each angle in angle L M N would be;
∠L + ∠M + ∠N = 180
∠M + ∠M + 2∠M = 180
4∠M = 180
∠M = 180/4
∠M = 45
∠M = ∠L = 45 degrees
∠N = 2 x 45 = 90
Therefore, the measure of ∠M and ∠L is 45 degrees. then the measure of ∠N is 90 degrees.

Fred is training for a cross-country race. At practice last week, he ran 6.25 miles in 1 1 4 hours. At that speed, how long would it take Fred to run 8.5 miles?
Answers
At the given speed it will take Fred 1.7 hours to run 8.5 miles.
An object's direction and rate of further travel are both regarded as parts of its velocity. By observing how fast and in which direction an object is moving, you may estimate its velocity.
Similar to speed, but also taking direction into account .Speed is hence directionless, but velocity denotes direction. Speed only offers a numerical representation of your speed.
Time taken by Fred to cover 6.25 miles = 1 1/4 = 1.25 hours
Speed of Fred = 6.25/1.25 = 5 miles per hour.
Distance to cover =8.25 miles
Time taken =8.25/5 = 1.7 hours.
Due to the addition of direction, velocity shows how quickly you are shifting your location. Because of this mismatch, if you travel very swiftly while your location stays the same, your velocity will only be 0.
Hence the time taken will be 1.7 hours.

your company wants to purchase swag gear for employees. they bought 5 sample merchandise at $ 450 each, 4 sample signs at $ 750 each, and 12 chromebooks with logo at $ 750 each. what is the average spent per article?
Answers
The company spent average amount $678.57 per article.
Average spent per article is calculated using the formula -
Average = sum of all observations ÷ total number of observations
In the question, observations are the different items bought by the company.
Amount spent on sample merchandise = 5 × 450
Amount spent on sample merchandise = $2250
Amount spent on sample signs = 4 × 750
Amount spent on sample signs = $3000
Amount spent on chromebooks = 12 × 750
Amount spent on chromebooks = $9000
Total amount spent = 2250 + 3000 + 9000
Total amount spent = $14,250
Number of articles = 5 + 4 + 12
Number of articles = 21
Average = 14,250 ÷ 21
